no WARBLERS 



also sings an ecstatic warbling on the wing; a tnfilErig 

 performance. The nest is built on the ground and, like 

 a Dutch oven, is roofed over with the entrance at one 

 side. The eggs, laid in May, are white, marked chiefly 

 at the larger end with brown.

The two Water-Thrushes and the Oven-bird are walking 

 Warblers, and the Water-Thrushes, furthermore, are 

 teeterers, nervously tipping tail and body with apparently 

 exhaustless energy. When migrating, the Northern 

 Water-Thrush often seeks refuge beneath the shrubbery 

 of our lawns, but when nesting it frequents the borders 

 of streams in deep woods, building its home on the ground 

 or in the roots of an upturned tree. Its call-note is a sharp 

 chink; its song a hurried rush of loud musical notes, clos- 

 ing abruptly. The 4-5 eggs, laid in the latter half of 

 May or early June, are white with numerous brown 

 markings chiefly about the larger end. 



Grinnell's Water-Thrush (5. n. notabilis), a slightly 

 larger and darker form, nests in the Northwest and is 

 casually found as a migrant on the Atlantic coast.
